Remarks

The return value is one of three possible values:

Return value	Rendering tier	Notes
0x00000000	0	No graphics hardware acceleration available for the application on the device.
0x00010000	1	Partial graphics hardware acceleration available on the video card. This corresponds to a DirectX version that is greater than or equal to 7.0 and less than 9.0.
0x00020000	2	A rendering tier value of 2 means that most of the graphics features of WPF should use hardware acceleration provided the necessary system resources have not been exhausted. This corresponds to a DirectX version that is greater than or equal to 9.0.

For more information on the definitions for the rendering tiers, see Graphics Rendering Tiers.

If the current thread does not have an associated Dispatcher object, one is automatically created.
